What it does
The Navigable Waters Regulations 1958 (WA) establish a comprehensive scheme for the safety, good order, and lawful use of Western Australia's navigable waters. Made under the Shipping and Pilotage Act 1967, Jetties Act 1926 and Western Australian Marine Act 1982 (together defined as "the Acts"), these regulations govern vessel operation, jetty use, mooring, obstruction removal, vessel registration, recreational skipper competency, and mandatory safety equipment. The regulations apply to all persons and vessels in navigable waters, defined broadly to include the territorial sea adjacent to the State, waters landward of that, and waters within State limits on which any vessel or marine craft can be navigated (r. 2(1)). Part II prescribes general good order rules: vessels must not be navigated to cause nuisance or damage (r. 14), lifesaving equipment and aids to navigation must not be interfered with (rr. 6, 7), and rubbish may not be deposited in navigable waters without permission (r. 8). Speed limits apply in the Swan and Canning Rivers between sunset and sunrise (10 knots, r. 19A). Diving operations require display of the International Code Flag “A” by day or three all‑round lights by night (r. 19C), and approaching vessels must keep at least 50 metres clear or proceed at slowest safe speed (r. 19E). Emergency vessels may be declared exempt from specified provisions (r. 3A, r. 19H). Part III regulates public jetties: vessels must not remain longer than necessary for embarking or discharging (r. 25), cargo cannot be left on jetties (r. 26), and vehicles and bicycles are restricted (r. 28). Part IV empowers the Department to direct mooring, berthing or removal of vessels (r. 38). Part 5 (inserted by SL 2025/215) creates a detailed regime for dealing with obstructions , vessels or other things that are hazards to safety or the environment, or placed in contravention of marine legislation (r. 40C). The CEO may issue remedy notices, investigate, remove obstructions, recover costs, and sell or destroy them (rr. 40F-45). Part 5A requires registration of registrable vessels (pleasure vessels fitted with a motor, excluding tenders) and prescribes fees, marking of registration numbers, hull identification numbers, and transfer procedures (rr. 45A-45F). Part 6 establishes recreational skipper’s tickets: persons under 16 generally cannot drive an RST vessel (propelled by more than 4.5 kW) without a ticket or direct supervision (r. 47A). Lifejacket wearing is mandatory for children aged 12 months to 12 years on pleasure vessels outside protected waters beyond 400 m from shore, for all persons on vessels less than 4.8 m outside protected waters beyond 400 m, and for all persons on personal watercraft (r. 50B). Pleasure vessels must carry appropriate lifejackets (r. 52A), distress signals (r. 52B), and, beyond 4 nautical miles from shore, a marine transceiver (r. 52BAA). An Emergency Position‑Indicating Radio Beacon or personal locator beacon is required outside protected waters beyond 400 m (r. 52BAB). Part VIII contains miscellaneous provisions including forms for warrants and orders to produce, disclosure of information by the Commissioner of Police, electronic notice giving, and an offence for unauthorised endorsement or alteration of infringement notices (rr. 68-74). Schedule 2 clarifies which things are vessels (boats, personal watercraft, paddle craft, sailboards, electric hydrofoil boards above 4.5 kW) and which are not (stand‑up paddle boards, surfboards, body boards, paddle boats, underwater propulsion devices, towed recreational equipment).
